Key specs explained for this dock

Display Support: Dual

A single connected display can reach a high resolution of 2560x1440 pixels at 50Hz. This provides sharp text and clear images for most office work. However, note that 4K resolution is not supported. When shopping for portable monitors, this limits your options for ultra-high definition content, focusing instead on standard high-definition clarity.
